I have a modded psone screen that i was going to use for another project that I can input the video into. I made a diagram, shown below, of what I was thinking would need to happen. I know its going to be more complex than what i have down there but is my diagram theoretically correct? Do these exist or am I just making up things? Is feasible to make or should I just forget about it? If it is possible than where would I get the parts and what parts would I really need? I'm sorry if I sound like an idiot or if I'm crazy. Any information would be great.

Thanks,
Notch
